Abstract:

A nickel-catalyzed cross-coupling reaction between readily available and structurally stable β-bromo amino acid esters and diphenyl disulfide has been developed, enabling the efficient synthesis of a series of novel cysteine derivatives. Employing the Ni(PPh34/1,10-phenanthroline catalytic system, the reaction proceeds smoothly under mild conditions, affording the target cysteine derivatives in moderate to good yields (58%~82%). Furthermore, this transformation utilizes a convenient one-pot procedure, successfully constructing the C(sp3)—S bond in a single step. The methodology has been successfully extended to the efficient formation of C(sp3)—O and C(sp3)—Se bonds, facilitating the modular synthesis of selenocysteine and serine derivatives. Featuring mild reaction conditions, operational simplicity, and excellent substrate compatibility, this strategy provides a new approach for synthesizing cysteine and serine derivatives with potential pharmaceutical value.
